Rewrite in simplest terms:−3(−9a−9)−4(8a−10)
Starting with the given expression: −3(−9a−9)−4(8a−10)
First, we simplify the expressions within the parentheses:
-3(−9a−9) = 27a + 27
-4(8a−10) = -32a + 40
Next, we substitute these simplified expressions back into the original equation:
27a + 27 -32a + 40
Finally, we combine like terms to simplify:
-5a + 67
Thus, the simplest form of the expression −3(−9a−9)−4(8a−10) is -5a + 67.
